How to save php variable into a 2D java script array

Question

How do I save php variable into a 2D JavaScript array.
inside php file :

for ($i=0;$i<$max;$i++) {
 $needHelp1[$i];
 $needHelp2[$i];
 }

I need to save the $needHelp1[$i] and $needHelp2[$i]to java script 2Darray called var needHelp = [] which is inside the same php file.

[ $needHelp1[0] , $needHelp2[1] 
  $needHelp1[1] , $needHelp2[1]
  $needHelp1[2] , $needHelp2[1] 
  $needHelp1[3] , $needHelp2[1] ]

I want the javascript array to be something like this.

Thanks.

json_encode is what your looking for,

var needHelp = <?php echo json_encode($needHelp1); ?>

When you run your php check the source and you should have a javascript array.

I didn't notice the output format you wanted. Construct your array the way you want it then json_encode. – shapeshifter Feb 13 at 4:09
